Be it known that l, JOHN I. LOGAN, a citizen of the United States,residing at Chicago, inthe county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Heating' Devices forVaporizing and Burning Kerosene, of which the following is aspecification.

My invention relates to heating devices forl burning vaporized oils, andthe Aprincipal object of the invention is tov provide a device of thistype suitable for burning kerosene. This is a desirable fuel on accountof its cheapness but so far as l am aware, no satisfactory burner of thevaporizing type has been heretofore devised for utilizing .kerosene in aheating device suitable for domestic purposes.

A'further object of the invention is to provide a device for vaporizingkerosene which may be placed'in a iirebox of the ordinary rangeor inother similar situations.

The invention has for further objects such other new and improvedconstructions, arrangements and devices in apparatus for burningvaporized oils as Will be hereinafter described and claimed.

The invention is illustrated in a preferred embodiment in theaccompanying drawings Wherein- Figure 1 is a side elevation of theburnerv showing also the oil supply tank and air pump' I Fig. 2 1s anend elevation of the burner.

Fig. 3 is a plan view of the Same.

Fig. E is a longitudinal sectional View on line l-e of Fig. 3.

Fig. 5 is a sectional plan on line 5-5 of Fig. tl is a longitudinal viewof a kitchen. range of ordinary construction showing the burner of myinvention arranged in the firebox.

Fig. 7 is a cross sectional-view taken on line J1-7 of Fig. 3, and

Fig. 8 is a view, in perspective, on an enlarged scale, of the nozzle ofthe starting vaporizer.

LikeJ characters of reference deslonate like parts in the severalfigures of therawin s.

g The device, as shown in the drawings, is designed particularly to beplaced in the fire-box 10 of an ordinary range 11 (Fig. 6).

' The burner 12 is a hollow body supported at opposite ends by metalplates 13, 14. The

bottom llof the burner is preferably rounded from slde to side and isformed with an viitakA duct 16 opening into the interior of the burnerat about the center thereof. The top 17 of the burner is also roundedand is formed with a plurality of parallel transverse ribs 18 formedwith burner slits 1). The ribs and slits preferably extend fartheraround the burner on one side than on the other, the top of the burnerbeing rounded over more on this side than on the other, and in arrangingthe device in the stove this side is placed at the side of the fire-boxadjacent the oven so that the fiume is deflected backwardly over theoven and toward chimney 20 (Fig. 6).

The kerosene is'kept in a tank 21 into which air is forced underpressure by means of a pump 22. 23 is a pipe leading from the kerosenetank to a vaporizing pipe 24 which extends longitudinally over theburner being supported on the end plates 13, 14. Pipe 2i is tapped intoa double valve casing 25 which is secured'to end plate 14. The casing 25is formed with a boss 26 providing a valve chamber 27 communicating byport ,23 with the main duct 29 of casing 25. Port 28 is controlled by .aneedle valve 30, the tapered part 31 of'avhich is adapted to eX- tendbeyond the port 28' so that the closing of the valve will clean out anyobstruction there may be in the port. The end of boss 25 is closed by abonnet 32. A branch pipe 33 leads from valve chamber 27 to a nozzle 34which is provided With a tip 35 formed with two perforations 36, 37, thebranch `pipe 33 being preferably coiled along side of the burner, asindicated at 38. 39 is a FAreceptacle preferably cast integrally withthe burner arranged below the starting vaporiner 33, 34,38 and adaptedto conta-in an absorbent material, such as asbestos, which is saturatedwith oil and the oil is ignited for the purpose of initially heating thestarting vaporizer. The perforations 36, 37 in the tip 35 are disposedso that a jet is projectedv from perforation 36 against the vaporizing.pipe Q4: at the end near the valves, whilevanother jet is projected fromperforation 37 against the coil 38 and the remote end of vaporizing pipe24.

The 4double valve casing 25 is formed with a vapor port 40 adapted to hecontrolled by a needle valve 41 threaded into a boss 42 formed on thevalve casing 25. Vapor is delivered through port 4U into the duct 16leading to the interior oi'the burner. Air enters the duct through theopening ail-in end plate 14. The kerosene tank 21 is preferably providedwith a pressure gage 44.

Operation: To start the device a little kerosene is poured intoreceptacle 39 on the side of the burner and ignited. `Valve 30 isopened. The flame beneath coil 38 is suflicient to vaporize the keroseneforced into the coil from tank' 22 by the air pressure andtwo jets offlame are projected against the vaporizing pipe 24, as shown in Fig. 3,one of these flames striking against the coil so that the startingvaporizer is kept in`operation even if the kerosene in` receptacle 39burns out. After the vaporizing pipe 24 has been heated sufficiently togenerate enough Vapor to start the burner v alve il is opened and thekerosene vapor passes from pipe 24 into the duct 16 vwhere it 'is mixedwith air and ptsses into the interior of the burner. Once t e be closedoil by shutting valve 30.

I have found that a burner of the form 1.
